Making the case for the #CorsiRosenthalBox with studies.

A simple thread.
"no U.S. Energy Star certified air cleaners have CADR values (for either tobacco smoke, dust, or pollen) matching the CADR value for the CR Box even on low speed "

On cost? 1/10th.

1019 to 1444 m3/hr CADR.

(600 to 850 ft3/min)

Published here:
tandfonline.com/doi/full/10.10… ImageImage
An incredibly thorough study published in February 2023, with all of its authors from @NIOSH.

With universal masking in a 3-ply cotton mask, exposure to the relevant aerosol size is reduced by 88 to 94%, with the #CorsiRosenthalBox.

73% w/ CRBox alone.

sciencedirect.com/science/articl… ImageImage
Very good thread on this study here:

Essentially the same NIOSH team investigated HEPA efficacy.

65% reduction with HEPA alone.

So, at a much cheaper price, the #CorsiRosenthalBox gets better results.

cdc.gov/mmwr/volumes/7…
But can HEPAs remove SARS-COV-2 from the air? Yes.

(Would #CorsiRosenthalBox do the same? Yes - faster and cheaper.

Has it been studied specifically for this? No. HEPAs barely have.

Do the same laws of physics apply? Yes.)

journals.asm.org/doi/full/10.11… Image
But can HEPAs really remove SARS-COV-2 from the air?

Yes - in a UK hospital, HEPAs were off. Cov1d was in the air. Turned on. No more CoV1d.

1000 m3/hour CADR.

Remember the first study?

1019 to 1444 m3/ hour for the CR box.

@MarinaC_Dyb and her fellow authors found a massive reduction in aerosols in OCCUPIED classrooms using the #CorsiRosenthalBox. Also found that ALL of the air went in.

No wonder they have rolled them out to 400 locations.

Study is linked here:

Oh for Pete's sake. @elonmusk has just killed another thread.

Let me add these manually.
"Also found that ALL of the air went in" - quoting above to go into a little more detail:

This answers, in a study, the concern that it just moves the air around. That it won't go into the filter.

It does, and this had to be pointed out.
The CDC, of which NIOSH is part of, has officially recommended 5 ACH, minimum, and that DIY Air Cleaners are effective at reducing the risk of transmission of Cov1d.

The #CorsiRosenthalBox is
specifically mentioned as part of that solution.

cdc.gov/coronavirus/20… ImageImageImage
@3M has studied it in their formal lab - and is officially on board:

news.3m.com/2022-02-24-3M-…
The famous UL, Inc testing the safety of the #CorsiRosenthalBox, to make sure it won't catch on fire.

It won't - even if the filters are loaded up.

(The link that is out on Twitter appears to be dead.)

ul.org/library/2988
"Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?"

Yes.

pubs.acs.org/doi/10.1021/ac… Image
Some have expressed surprise that this was found.

Dr. Corsi explains:

And the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRi
A thesis - a study, that found 7 PFAs, and exposure to for both dog and human. (@ShellyMBoulder collaborated).
elischolar.library.yale.edu/ysphtdl/2161/ Image
How do we know that dogs are affected? Because it is dogs that get experimented on.

And not to get too personal, but my dog has stage 4 chronic kidney disease. CKD can be caused by PFAs.

Did I do that? Or at least not prevent it? A lot of

wunc.org/health/2021-05… Image
years with no air filtration.

But hey - she is 15 years old, and it could be just old age.

In any event, I don't want to go into any more detail, but now I know better.

But besides PFAs, dogs can catch Cov1d.

As can cats.

In fact, from the study, we should see our cat as part of our family regarding virus transmission.

Can a cat or dog wear a mask?

Yes, with training.

But what if you could reduce their risk of catching Cov1d without all that? Image
And the risk to the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRosenthalBox as the centerpiece of your family pandemic prevention protocol.

And it worked.

Thread of debunking the myth that "babies should not be masked."

A baby uninfected is better than a baby infected.

If you oppose masking babies, you are immediately for infecting babies.

Let's get to it. A most excellent instruction page on how to mask babies. Suck it antimaskers.
This solves an equity problem.

Not everyone has the money or technical skill to build a baby buggy PAPR.

Just like not everyone has the money to buy an adult PAPR.

Are you for people on SNAP being able to protect their babies? Or not?

Most can rustle up the money to buy some uber cute baby masks!

This is the link from the baby zine.

These need to be fit tested.

Now, let's get into the good stuff. The "OMG Laz has gone too far! We've got him!"

You better bring your A game.

If you are Covid Aware you have probably been avoiding the dentist. Well, the dental studies have come to you.

This edition? #CovidAwareSoReducingDentalVisits - Water flossing (WF) edition.

Or, as I like to think of it, the Gum Salon.

Thread.
Flossing is necessary for those super tight contact points as you see in the above thread, and is great to remove plaque down 1 mm deep in the gum line (gently).

InterDental Brushes are fantastic and go down 2-3 mm into the gum line to remove plaque.

And WFs in general, are, well, amazing!!

They basically go back and forth with InterDental Brushes on which is better as far as being the top of the food chain for overall cleaning of the space between your teeth.

But.

If you have gum recession, you may have this Image

I remember why I got going on this run of dental care threads.

I got a root canal, and then a cleaning. The hygienist told me that masks cause dental problems. I didn't say anything, but that's complete horse...puckies.

#CovidAwareSoReducing - Plaque/ Toothbrush edition.
It upset me, to be frank, and when I get fired up, I act. Since she is very nice, albeit uneducated on masking, I let it go - with her.

But I decided to figure out what I was doing wrong.
And it was everything.

I was brushing and flossing losing 1-2 microns of enamel
after brushing/ flossing, immediately after eating.

I was nursing sweet Monster/ Starbucks/ my own sweet coffee drinks ALL DAY LONG. A bubbling vat of acid in my mouth.

I was doing the Dr. Ellie Phillips system - but just missing the boat on the importance of replacing sugar

#CovidAwareSoReducingDentalVisits - less mouth open = less 'vid risk.

I am a GREAT flosser. My family thought we had genetic gum disease.

Below we can see rubber stick on the left, floss on the right, and a InterDental Brush (IDB) in the middle.

See the problem?
/1 Image
A couple more example pics on why I am sick to my stomach thinking of all that money wasted.

We THOUGHT we had great dentists. Not a single one mentioned IDBs, and how the bristles allow all interdental spaces to be reached.

And it gets better!

/2 Image
Image
IDBs actually reach down in between the gum and teeth - 2-3 mm. Floss? Only 1-2 mm.

As plaque grows down into and touches your gums, that's what causes them to get inflamed - and begin to retreat (very simplified).

If you brush that space? Problem solved.

/3 Floss, Interdental Brushes, and Waterpics Use all of them - floss works great for those narrow spaces. Interdental Brushes (IDB) work great in larger spaces. Waterpics work great immediately after eating, as you want to wait for an hour eating acidic/sweet just like regular brushing. It is a mistake to NOT IDB. Multiple studies indicate IDB is good, including this RCT where IDB was better than flossing (free version - great how to brush) - with people with chronic periodontitis. Students found IDB to be better. But IDB is better than rubber picks is better than floss. IDB way better ...

Covid Aware Teeth

The Calcium Lactate Rinse. Cheap, super easy to do - and it really enhances your fluoride uptake to re-enamel your enamel.

It's just not very well known, despite being very well supported within studies - and very cheap.

Mix 1/8 tsp with 1 oz water. Shake
thoroughly, till the granules disappear. Takes a few or 20 shakes, then just wait. Rinse for 1 minute. Spit out.

Immediately brush with fluoride or fluoride rinse.

There might be a better powder

I use the same 1 oz shaker as my stannous fluoride rinse comes in.

(That fluoride rinse was $4 cheaper at my dentist than this $24.

My Prevident 5000 ppm actually did not need a prescription - if bought from my dentist, as a couple of side notes.)

.On the one hand, we have study after study showing 36% or so rate of LongCovid.

On the other, we have the WHO saying the rate of LongCovid is only 6%.

I got curious. What drugs are the WHO smoking - and can I get some?

🧵. Image
My 36% comes from the latest massive meta:
eatg.org/hiv-news/more-…

But what about that 6%?

Turns out it's this old chestnut from 2022.

And there are such major players on it...so many I can't even screenshot them all.

But I fear no title - and neither

jamanetwork.com/journals/jama/… Image
will you.

The problem with this 6%? There are 200+ symptoms in the LongCovid symptoms constellation.

This study focuses on three clusters.

Which is incredibly vague, which is normal for the WHO.

So, after digging through the f***ing supplement, there are a few symptoms Image
